Abstract

En sliteringmontasje (22) for en luftkanon omfatter en støttering (128) som har en opptaksutsparing (130) med en første lengde dannet i en overflate av en ende av støtteringen (128). En elas- tisk ring (124) ligger nær opp til en ende av opptaksutsparingen (130). En slitering (126) er anbrakt i opptaks- utsparingen (130) og har en andre lengde som er større enn den første lengde, slik at et parti av sliteringen (126) overlapper enden av støtteringen (128), og dermed dekker og deformerer den elas- tiske ring (124). Sliteringen (126) er dannet av et tynt, lavfriksjons, slitas- Jebestanding plastmateriale med slike dimensjoner at sliteringen (126) ikke flyter plastisk under installasjon i opptaksutsparingen (130). Installasjon utføres ved å feste et konusverktøy nær opp til tetningssporet (82). Sliteringen installeres med et utvidende skyver- verktøy, over konusverktøyet og inn i opptaksutsparingen (130).
